The California Department of Water Resources is currently upgrading the seismic safety of Perris Dam.

Construction to strengthen the foundation began in October 2014 and is expected to continue for three years.

In 2005, DWR identified potential seismic safety risks in a section of the foundation of the dam and lowered the lake level to ensure maximum public safety until dam repairs are made. The reservoir has since been further drawn down to meet drinking water demands during the prolonged drought.

DWR is working closely with state and federal fish and wildlife agencies to protect local wildlife and environmentally sensitive areas during construction. DWR is also working closely with the California Department of Parks and Recreation to minimize recreation impacts to the public.

The Lake Perris State Recreation Area will remain open during construction for boating, fishing and other recreational activities. Lake access and area closure information may be found here.
